Показать описание
How do plants transport sucrose? This video explains the transportation of sucrose in the phloem vessels (also called the sieve tubes) and the role of the companion cells in this transportation. It also mentions how the phloem and the xylem work together to ensure efficient transportation of sucrose.

Why does the concentration of sucrose in the phloem is higher than in the mesophyll cell that is constantly making it?


Thank you so much in advance.🥰

thanks for the video, super helpful. but my question is on the sucrose loading;
why are the hydrogen protons necessary? and why are the sucrose ions on the other side of the companion cell yet they just entered?
